Answer and Explanation

The Correct Answer is ["0.3"]

Calculating the Lidocaine Dose

Problem: Administer 50 mg of lidocaine IV bolus. The available concentration is 200 mg/mL.

Steps:

Set up a proportion:

We want to find the number of milliliters (mL) needed.

We know the desired dose (50 mg) and the concentration of the medication (200 mg/mL).

Proportion:

x mL / 50 mg = 1 mL / 200 mg

Cross-multiply:

200x = 50

Solve for x:

x = 50 / 200

x = 0.25

Answer: The nurse should administer 0.3 mL of lidocaine per dose(rounded to the nearest tenth).

Correct Answer is B

Explanation

A) Explain the purpose for the medications:
While explaining the purpose of the medications is important, it is crucial first to understand the reason behind the client's refusal. This can help tailor the explanation to address specific concerns or misconceptions.

B) Ask the client why he is refusing to take the medications:
Asking the client about their reasons for refusing the medications is a critical first step. This approach allows the nurse to address any concerns, educate the client, and potentially find alternative solutions or treatments that the client may be more willing to accept.

C) Tell the client the physician wants him to take the medications:
Simply telling the client that the physician wants them to take the medications does not address the underlying reasons for the refusal. It is important to engage with the client to understand their perspective and address any concerns they might have.

D) Document that the client refuses the medications:
Documentation of the refusal is necessary for legal and medical records, but it should not be the initial action. Understanding the client’s reasons for refusal and attempting to address those reasons should be prioritized before documenting the refusal.

Correct Answer is ["0.2"]
